Characteristics And Motivational Factors Of American Equine Journalists, Zoe B. Bowden, Ricky W. Telg, Lisa K. Lundy

Journal of Applied Communications

The purpose of this study was to identify the demographic characteristics, career motivations, and professional development of American equine journalists. An online survey was distributed to equine journalists identified through their professional organizational membership. Descriptive statistics were used to analyze the data. Equine journalists were found to be predominately female, Caucasian, and averaged 53 years old. Nearly half were exposed to the equine industry prior to their career and have been working in the industry for over 15 years. Respondents were well educated and were most motivated towards their career as an equine journalist because of their interest in horses ...

Development And Utilization Of An Isolation Box Test To Characterize Personality Traits Of Dairy Calves, Megan Marie Woodrum Setser, Heather W. Neave, Eric S. Vanzant, Joao H. C. Costa

Animal and Food Sciences Faculty Publications

The use of an isolation box test (IBT) to characterize personality traits has been used in non-bovine species with success. We aimed to develop an IBT for dairy calves and determine if the behavioral responses to an IBT were associated with personality traits found from traditional tests (novel person, novel object, and a startle tests) and average daily gain (ADG; Kg/d) through weaning. Calf movement while in the IBT was measured via accelerometers attached to 5 locations on the exterior of the box. A total movement index (TMI) was calculated based on accelerometer readings during the IBT. We performed ...

Preliminary Survey And Diet Analysis Of Anurans In The Riparian Zone Of Calayagon Watershed, Agusan Del Norte, Philippines, Jenessa Verna B. Salo, Chennie L. Solania

Journal of Bioresource Management

Watersheds are critical habitats for a diverse array of organisms. Among all the fauna, anurans are excellent biological indicators of environmental health. The community structure is often associated with a relationship between species diversity and diet. An anuran survey was conducted along riparian zones of three selected barangays of Calayagon Watershed (Guinabsan, Rizal, and Malpoc), Philippines. Extensive opportunistic methods for a total of 480 man-hours were spent traversing the area. A total of 195 individuals, consisting of seven species from four families, were recorded. Seventy-two percent of the individual species were regarded as Least concern, and 14 % were Near-threatened. Of ...

Parasite Dynamics In Untreated Horses Through One Calendar Year, Ashley E. Steuer, Haley P. Anderson, Taylor Shepherd, Jessica A. Scare, Holli S. Gravatte, Martin K. Nielsen

EKU Faculty and Staff Scholarship

Background: Horses are host to a plethora of parasites. Knowledge of the seasonality of parasite egg shedding and transmission is important for constructing parasite control programs. However, studies describing these patterns are sparse, and have largely been conducted only in the United Kingdom. This study evaluated strongylid egg shedding patterns and transmission dynamics of Strongylus vulgaris in naturally infected and untreated mares and foals through one calendar year in Kentucky, USA. The study also investigated the existence of a peri-parturient rise (PPR) in strongylid egg counts in foaling mares and collected information about Strongyloides westeri and Parascaris spp. in the ...


Temperature-Induced Multi-Species Cohort Effects In Sympatric Snakes, Richard B. King 2022 Northern Illinois University

Temperature-Induced Multi-Species Cohort Effects In Sympatric Snakes, Richard B. King

Faculty Peer-Reviewed Publications

In reptiles, reproductive maturity is often determined by size rather than age. Consequently, growth early in life may influence population dynamics through effects on generation time and survival to reproduction. Because reproductive phenology and pre- and post-natal growth are temperature dependent, environmental conditions may induce multi-species cohort effects on body size in sympatric reptiles. I present evidence of this using 10 years of neonatal size data for three sympatric viviparous snakes, Dekay's Brown snakes (Storeria dekayi), Red-bellied Snakes (S. occipitomaculata), and Common Garter snakes (Thamnophis sirtalis). End-of-season neonatal size varied in parallel across species such that snout–vent length ...


Regional Minimums In The U.S. Beef Complex, Elliott James Dennis, Bradley D. Lubben 2022 University of Nebraska - Lincoln

Regional Minimums In The U.S. Beef Complex, Elliott James Dennis, Bradley D. Lubben

Center for Agricultural Profitability

This report shows how the currently proposed policies differ; shows how these policies have aligned with historical market behavior; provides alternative specifications to regional minimums; and suggests policy alternatives to regional minimums.

The main purpose of this report is to show how current and potential alternative specifications of regional minimums would have historically aligned with observed market behavior. However, the fundamental question in the debate of the validity and effectiveness of regional minimums first rests on whether robust price discovery has historically occurred over time and within each USDA-AMS region. If there has been a lack of price discovery during ...


Nest Records Of Nebraska Birds, Wayne J. Mollhoff 2022 Ashland, NE

Nest Records Of Nebraska Birds, Wayne J. Mollhoff

Zea E-Books Collection

Nebraska Ornithologists' Union Occasional Paper Number 9

This publication is an attempt to provide a synopsis of the breeding information accumulated in the past two centuries. As with any compilation like this, other workers would likely come to different conclusions in choosing which records to accept and which to reject. I have tried to state the reasons for my decisions as clearly as possible. Most difficult to categorize are species which are not well documented. Hopefully by laying out the evidence I could find, others will be prompted to do more research, uncover definitive proof, and put more of our ...


Climate Drives Long-Term Change In Antarctic Silverfish Along The Western Antarctic Peninsula, Andrew D. Corso, Deborah K. Steinberg, Sharon E. Stammerjohn, Eric J. Hilton 2022 Virginia Institute of Marine Science

Climate Drives Long-Term Change In Antarctic Silverfish Along The Western Antarctic Peninsula, Andrew D. Corso, Deborah K. Steinberg, Sharon E. Stammerjohn, Eric J. Hilton

VIMS Articles

Over the last half of the 20th century, the western Antarctic Peninsula has been one of the most rapidly warming regions on Earth, leading to substantial reductions in regional sea ice coverage. These changes are modulated by atmospheric forcing, including the Amundsen Sea Low (ASL) pressure system. We utilized a novel 25-year (1993–2017) time series to model the effects of environmental variability on larvae of a keystone species, the Antarctic Silverfish (Pleuragramma antarctica). Antarctic Silverfish use sea ice as spawning habitat and are important prey for penguins and other predators. We show that warmer sea surface temperature and decreased ...

The Status Of Virginia’S Public Oyster Resource 2021, Melissa Southworth, Roger L. Mann

Reports

The Virginia Institute of Marine Science (VIMS) monitors recruitment of the Eastern oyster, Crassostrea virginica (Gmelin, 1791), annually from late spring through early fall, by deploying spatfall1 (settlement and recruitment of larval oysters to the post metamorphic form termed spat) collectors (shellstrings) at various sites in three Virginia western Chesapeake Bay tributaries. The survey provides an estimate of a particular area’s potential for receiving a "strike" or settlement (set) of oysters on the bottom and helps describe the timing of recruitment events in a given year. Information obtained from this monitoring effort provides an overview of long-term recruitment trends ...

Zoonotic Pathogens From Illegally Traded Wildlife Justify Adopting The One Health Perspective In Disease Response, Marianne Allison G. Lee, Vinyl Joseph S. Valeza, Jonathan Patrick H. Yan, Ronald Allan L. Cruz

Biology Faculty Publications

Recent studies have described a direct relationship between the illegal wildlife trade (IWT) and the prevalence of zoonotic pathogens in human populations. In the Philippines, the Philippine Integrated Disease Surveillance and Response (PIDSR) framework outlines the monitoring, response, and management of disease outbreaks, but needs to be updated in the wake of zoonoses from IWT. Here, we identified zoonotic pathogens that may be introduced to human populations through the IWT, pinpointed potential outbreak hotspots, and provided recommendations on how to improve the Philippines’ public health response while considering One Health. Using seizure data from the Biodiversity Management Bureau (DENR-BMB) covering ...

Form Of Supplemental Selenium Affects The Expression Of Mrna Transcripts Encoding Selenoproteins, And Proteins Regulating Cholesterol Uptake, In The Corpus Luteum Of Grazing Beef Cows, Sarah N. Carr, Benjamin R. Crites, Joy L. Pate, Camilla H. K. Hughes, James C. Matthews, Phillip J. Bridges

Animal and Food Sciences Faculty Publications

Selenium (Se)-deficient soils necessitate supplementation of this mineral to the diet of forage-grazing cattle. Functionally, Se is incorporated into selenoproteins, some of which function as important antioxidants. We have previously shown that the source of supplemental Se; inorganic (sodium selenite or sodium selenate; ISe), organic (selenomethionine or selenocysteine; OSe) or 1:1 mix of ISe and OSe (MIX), provided to Angus-cross cows affects concentrations of progesterone (P4) during the early luteal phase of the estrous cycle. In this study, we sought to investigate (1) the effect of form of Se on the expression of mRNA encoding selenoproteins in the ...

Research outputs 2022 to 2026

Islands can be powerful demonstrations of how destructive invasive species can be on endemic faunas and insular ecologies. Oceanic islands in the eastern Indian Ocean have suffered dramatically from the impact of one of the world’s most destructive invasive species, the black rat, causing the loss of endemic terrestrial mammals and ongoing threats to ground-nesting birds. We use molecular genetic methods on both ancient and modern samples to establish the origins and minimum invasion frequencies of black rats on Christmas Island and the Cocos-Keeling Islands. We find that each island group had multiple incursions of black rats from diverse ...
